FIG. 1 and FIG. 2 are schematic diagrams of possible application scenarios in the embodiments of the present application. FIG. 1 exemplarily shows one network device and two terminal devices. Optionally, the wireless communication system may include multiple network devices and the coverage of each network device may include other numbers of terminal devices. The present invention The embodiment does not limit this.

In addition, the wireless communication system may also include other network entities such as a mobile management entity (MME), a serving gateway (S-GW), a packet data network gateway (P-GW), etc. However, the embodiment of the present invention is not limited thereto.

The terminal device 20 and the terminal device 30 can communicate in a D2D communication mode. When performing D2D communication, the terminal device 20 and the terminal device 30 directly communicate through a D2D link, that is, a side link (SL). For example, as shown in FIG. 1 or FIG. 2, the terminal device 20 and the terminal device 30 directly communicate through a side link. In FIG. 1, the terminal device 20 and the terminal device 30 communicate through a side link, and transmission resources are allocated by the network device; in FIG. 2, the terminal device 20 and the terminal device 30 pass through a side link For communication, the transmission resources are independently selected by the terminal equipment, and no network equipment is required to allocate transmission resources.

In V2X communication, X can refer to any device with wireless receiving and transmitting capabilities, such as but not limited to slow-moving wireless devices, fast-moving in-vehicle devices, or network control nodes with wireless transmitting and receiving capabilities. It should be understood that the embodiments of the present invention are mainly applied to the scenario of V2X communication, but may also be applied to any other D2D communication scenario, and the embodiment of the present invention does not limit this.

There are two transmission modes defined in the Internet of Vehicles, namely transmission mode 3 (mode 3) and transmission mode 4 (mode 4). The transmission resources of the terminal device in mode 3 (referred to as mode 3) are allocated by the base station, and the terminal device sends data on the side link according to the resources allocated by the base station; the base station can allocate resources for the terminal device for a single transmission. It is also possible to allocate terminal resources for semi-static transmission. If a terminal device in transmission mode 4 (referred to as mode 4) has the listening capability, it uses the sensing and reservation methods to transmit data. If it does not have the listening capability, it randomly selects transmission in the resource pool. Resources. A terminal device with a listening capability obtains a set of available resources by listening in a resource pool, and the terminal device randomly selects a resource from the set for data transmission. Because the services in the IoV system have periodic characteristics, terminal devices usually use semi-static transmission, that is, after a terminal device selects a transmission resource, it will continue to use the resource in multiple transmission cycles, thereby reducing resource reuse. Selection and the probability of resource conflicts. The terminal device will carry the information for the next transmission resource in the control information transmitted this time, so that other terminal devices can determine whether this resource is reserved and used by the terminal device by detecting the control information of the terminal device. The purpose of reducing resource conflicts.

Each of the above resource pools used by the terminal device during data transmission is pre-configured or network-configured. When the terminal device is out of network coverage, it can only use the pre-configured resource pool to perform data transmission with other terminal devices. When the terminal device is within network coverage, data can be transmitted to terminal devices outside the network coverage using a pre-configured resource pool, or data transmission can be performed to other terminal devices within the network coverage using the resource pool configured by the network. However, in NR, higher requirements are imposed on the data transmission performance between terminal devices, such as expecting higher throughput, lower latency, higher reliability, larger coverage, and more flexibility. Resource allocation methods, etc. Therefore, in addition to these pre-configured resource pools, the network device can also configure additional resource pools for terminal devices for data transmission between terminal devices within network coverage and terminal devices outside network coverage.

The embodiment of the present application proposes that the first terminal device sends the resource pool configuration information of the resource pool, so that the second terminal device can use the resource pool to communicate with the first terminal device. The resource pool may be an additional resource pool in addition to the pre-configured resource pool. Since the additional resource pool is configured, and the first terminal device may notify the resource configuration information of the additional resource pool to other terminal devices, More terminal devices can obtain the information of the resource pool and use the resource pool for communication, so the data transmission performance between the terminal devices is improved to a certain extent.

FIG. 3 is a flowchart interaction diagram of a resource configuration method according to an embodiment of the present application. The method shown in FIG. 3 may be executed by a first terminal device and a second terminal device. The first terminal device may be, for example, the terminal device 20 or the terminal device 30 shown in FIG. 2, and the second terminal device may be, for example, a figure The terminal device 30 or the terminal device 20 shown in 2.

In 330, the second terminal device receives resource pool configuration information of the target resource pool.

In 340, the second terminal device determines the target resource pool according to the resource pool configuration information.

The target resource pool is used to communicate with the first terminal device.

In the embodiment of the present application, the target resource pool may be, for example, an additional resource pool configured by the network device for the terminal device for communication. In other words, the target resource pool is a resource pool other than a pre-configured resource pool for terminal devices to perform D2D communication.

Optionally, the first terminal device may be a terminal device in a cell, and the second terminal device may be a terminal device outside the cell. Here, the second terminal device may be located outside the cell where the first terminal device is located and does not belong to other cells, or the second terminal device may be located in another cell, that is, the second terminal device and the cell in which the first terminal device is located are different.

When the first terminal device is a terminal device in a cell, the first terminal device may receive the resource pool configuration information of the target resource pool from a network device, so as to perform data transmission in the target resource pool. However, if a second terminal device exists outside the cell, since the second terminal device cannot receive the resource pool configuration information sent by the network device, the second terminal device cannot use the target resource pool for data transmission. At this time, according to the method in the embodiment of the present application, the first terminal device may send the resource pool configuration information of the target resource pool to the second terminal device, so that the second terminal device can learn the existence of the target resource pool, and thus is performing This target resource pool can be used during data transfer.

The first terminal device may, for example, send the resource pool configuration information through a first lateral transmission channel. Optionally, the transmission resource of the first lateral transmission channel may be a transmission resource pre-configured or configured by a network device, or may be one transmission resource in a pre-configured resource pool. And, optionally, the first transmission resource may be used only to transmit the resource pool configuration information, and not used to transmit other side data.

In an implementation manner, the first side-link transmission channel may be a physical side-link broadcast channel (Physical Sidelink Broadcast Channel, PSBCH). The PSBCH directly carries resource pool configuration information of a target resource pool.

In another implementation manner, the first lateral transmission channel may be a physical lateral link control channel (Physical Sidelink Control Channel, PSCCH), and the physical lateral link shared channel (Physical Sidelink shared Channel) scheduled by the PSCCH, (PSSCH) carries the resource pool configuration information; or, the first lateral transmission channel may be a PSSCH, and the PSSCH carries the resource pool configuration information.

In the embodiment of the present application, the resource pool configuration information of the target resource pool may include at least one of the following information:

Information of the carrier on which the target resource pool is located;

A positional relationship between a control channel resource and a data channel resource in the target resource pool;

The control channel resource and the time domain resource of the data channel resource are adjacent or non-adjacent;

Information of the demodulation reference signal DMRS pattern of the target resource pool;

Information about the basic parameter set of the target resource pool;

It should be understood that in the embodiments of the present application, the time domain unit may be a subframe, a time slot, a symbol, etc., and the frequency domain unit may be a subband, a resource block group (RBG), or a physical resource block (Physical resource block). PRB) and so on. One subband includes a plurality of consecutive PRBs, and one RBG includes a plurality of consecutive PRBs.

The related information of the target resource pool carried in the resource pool configuration information is described in detail below.

In NR-V2X, multiple carriers can be supported. Within a cell, network equipment can configure resource pool information on each carrier. Outside the cell, the resource pool information on some carriers can be pre-configured. Therefore, the resource pool configuration information sent by the terminal equipment in the cell may include carrier information to indicate which carrier the target resource pool is located in. Optionally, the information of the carrier on which the target resource pool is located may include the number of the carrier on which the target resource pool is located. And, optionally, the resource pool configuration information sent on the first carrier may be used to indicate the resource pool on the second carrier.

Optionally, if multiple Bandwidth Part (BWP) can be configured on one carrier, the resource pool configuration information may further include a BWP index, which is used to indicate which BWP the target resource pool is located in.

Optionally, the information of the time domain resources occupied by the target resource pool may include:

The size of the time domain unit in the target resource pool, such as the number of time domain symbols in each subframe;

The number of time domain units in the target resource pool, such as the number of subframes included in the target resource pool;

The size of the time domain resources occupied by each control channel resource (such as the number of time domain symbols occupied), such as the number of time domain symbols occupied by each control channel resource in the target resource pool in a time domain unit ;

The size of the time domain resources occupied by each data channel resource (such as the number of time domain symbols occupied), for example, the number of time domain symbols occupied by each data channel resource in a target resource pool in a time domain unit ;

At least two pieces of information in the time domain position of the first transmission resource in the target resource pool, the time domain position of the last transmission resource in the target resource pool, and the time domain length of the target resource pool, for example, when When the target resource pool includes continuous time domain resources, the information of the time domain resources occupied by the target resource pool may include the time domain position of the first transmission resource in the target resource pool and the time domain length of the target resource pool.

Optionally, the information of the time domain resources occupied by the target resource pool may further include information of the time domain units occupied by the target resource pool, such as which time domain units the target resource pool includes. At this time, optionally, the information of the time domain unit occupied by the target resource pool may be represented by a bitmap, and a value on each bit in the bitmap indicates whether the time domain unit corresponding to the bit belongs to The target resource pool.

For example, the bitmap includes 10 bits, and each of the 10 bits corresponds to a subframe or a time slot. Wherein, a value of 1 indicates that the subframe or time slot corresponding to the bit belongs to the target resource pool, and a value of 0 indicates that the subframe or time slot corresponding to the bit does not belong to the target. Resource pool.

Optionally, the bitmap may be used to indicate whether a subframe or a time slot within each fixed duration belongs to the target resource pool. For example, the fixed duration is one radio frame, and each radio frame includes 10 subframes. The 10 bits in the bitmap correspond to the 10 subframes in each radio frame one by one. The value on the bit is used to indicate whether the subframe corresponding to the bit belongs to the target resource pool. A radio frame period includes 1024 radio frames, and the subframes belonging to the target resource pool in each radio frame can be determined through the bitmap, that is, the positions of those subframes belonging to the target resource pool in each radio frame Are the same. For example, the bitmap is 1111110000, which indicates that the first to sixth subframes in each radio frame in a radio frame period belong to the target resource pool.

For another example, the bitmap includes 14 bits, and the 14 bits can indicate whether 14 time domain symbols in subframe 1 belong to the target resource pool, and a value of 1 in the bit indicates the bit. The time domain symbol corresponding to the bit belongs to the target resource pool. When the value on the bit is 0, it indicates that the time domain symbol corresponding to the bit does not belong to the target resource pool. For example, the bitmap is 10101010101010, which means that the target resource pool includes symbols 0, 2, 2, 4, 6, 8, 8, and 12 in the subframe 1.

Optionally, the information of the time domain resources occupied by the target resource pool may include multiple bitmaps, which are collectively used to indicate the time domain units occupied by the target resource pool. For example, the information of the time domain resources occupied by the target resource pool includes a first bitmap and a second bitmap. The first bitmap includes 14 bits, which respectively correspond to 14 time-domain symbols in each subframe, and is used to indicate which time-domain symbols in each subframe belong to the target resource pool. The second bitmap includes 10 bits, one to one corresponding to the 10 subframes in each radio frame, and is used to indicate which subframes in each radio frame belong to the target resource pool. Therefore, by using the second bitmap, it is possible to determine which subframes in each wireless frame in a wireless frame period belong to the target resource pool. Through the first bitmap, it is possible to further determine each of these subframes. Which time domain symbols belong to the target resource pool.

Optionally, the information of the frequency domain resources occupied by the target resource pool may include:

The size of the frequency domain unit in the target resource pool, such as the number of PRBs in each subband;

The number of frequency domain units in the target resource pool, such as the number of subbands included in the target resource pool;

The size of the frequency domain resources occupied by each control channel resource (such as the number of PRBs or subbands occupied), such as the number of PRBs occupied by each control channel resource in the target resource pool in a frequency domain unit;

The size of the frequency domain resources occupied by each data channel resource (such as the number of PRBs or subbands occupied), such as the number of PRBs occupied by each data channel resource in a target resource pool in a frequency domain unit;

At least two pieces of information in the starting position of the frequency domain of the target resource pool, the ending position of the frequency domain of the target resource pool, and the size of the frequency domain occupied by the target resource pool, when the target resource pool includes continuous frequency domain resources The information of the frequency domain resources occupied by the target resource pool may include the frequency domain position of the first transmission resource in the target resource pool and the frequency domain width of the target resource pool.

For example, the start position in the frequency domain of the target resource pool is the index of the first subband in the target resource pool, and the end position in the frequency domain of the target resource pool is the index of the last subband in the target resource pool. The size of the frequency domain occupied by the resource pool is the number of subbands included in the target resource pool.

Optionally, the positional relationship between the control channel resources and the data channel resources (or the structure of the target resource pool) in the target resource pool includes time division between the control channel resources and the data channel resources. Use or frequency division multiplexing.

Further, the resource pool configuration information of the target resource pool may include the index of the position relationship. For example, when index 1 is included, it indicates that the control channel resource and the data channel resource are time-division multiplexed. When index 2 is included, it indicates Frequency division multiplexing between control channel resources and the data channel resources.

In the Internet of Vehicles system, when terminal equipment performs data transmission, data transmission and transmission of corresponding resource scheduling information may adopt a frequency division multiplexing (FDM) or time division multiplexing (TDM) method.

Specifically, when the frequency division multiplexing method is adopted, there are two configuration modes for a resource pool for transmitting resource scheduling information and a resource pool for transmitting data, that is, frequency domain adjacent (adjacent) and non-adjacent (non-adjacent) adjacent).

For example, in the case of adjacent in the frequency domain shown in FIG. 4, the control channel resources used for transmitting resource scheduling information, and the data channel resources corresponding to the control channel are adjacent in the frequency domain. The entire system bandwidth is sub-band (sub-band) as the granularity. Each sub-band includes multiple consecutive PRBs. The first PRB and the second PRB in each sub-band can be used to transmit the control channel, and the remaining PRBs can be used. Used to transmit data channels. There is a one-to-one correspondence between data channel resources and control channel resources. The resource scheduling information transmitted on the control channel resources is used to schedule data transmission on the data channel resources corresponding to the control channel resources, and the start of the data channel resources The location is determined by the location of its corresponding control channel resource. Data channel resources can occupy one subband (for example, the data channel resources on subframe 2 are located in subband 1), or they can span multiple subbands (for example, the data channel resources on subframe 4 are located in subband 2 and subbands) 3). When a data channel resource occupies multiple subbands, the data channel resource is continuous in the frequency domain in multiple subbands, and can occupy control channel resources in other subbands, and the control channel resource corresponding to the data channel resource is the data channel. The control channel resource in the first subband where the resource is located, for example, the data channel resource on subframe 4 in FIG. 4 occupies two adjacent subbands (subband 2 and subband 3), and the corresponding control channel The resource is a control channel resource in the first subband (subband 2).

For example, in the case of non-adjacent in the frequency domain shown in FIG. 5, the control channel resources and their corresponding data channel resources are not adjacent in the frequency domain, and the data channel resources and control channel resources are configured independently. However, the position of the data channel resource and the position of the control channel resource are still one-to-one, the resource scheduling information transmitted on the control channel resource is used to schedule data transmission on the data channel resource corresponding to the control channel resource, and the data channel The starting position of the resource may be determined by the corresponding position of the control channel resource. The data channel resource can occupy one subband (for example, the data channel resource is shown in subband 1 on subframe 2), or multiple control channel resources can be occupied as the control channel in the first subband where the data channel resource is located. Resources, for example, the data channel resources on subframe 4 in Figure 5 are located in two adjacent subbands (subband 2 and subband 3), and the corresponding control channel resource is the first subband (subband 2) Control channel resources within.

When the time division multiplexing method is adopted, for example, as shown in FIG. 6, the first terminal device sends its own control channel resource, PSCCH, on subband 3 of subframe 1, and the data channel resource corresponding to the control channel resource, that is, PSSCH is on the sub-channel. It is transmitted on subband 2 of frame 4. The side link control information (SCI) carried on the control channel resource can carry the information of its corresponding data channel resource; the second terminal device in subframe 1 Subband 4 sends its own control channel resource, and the data channel resource corresponding to the control channel resource is transmitted on subband 3 of subframe 5. The SCI carried on the control channel resource can carry information about its corresponding data channel resource; The third terminal device sends its own control channel resource on subband 3 of subframe 2. The data channel resource corresponding to the control channel resource is transmitted on subband 2 of subframe 6. The SCI carried on the control channel resource can be carried. Information about its corresponding data channel resources.

The resource pool configuration information of the target resource pool may carry the position relationship between control channel resources and data channel resources in the target resource pool. After receiving the resource pool configuration information, the second terminal device may know that Whether the control channel and its corresponding data channel are transmitted in the resource pool in the manner shown in FIG. 4 or FIG. 5 or in the manner shown in FIG. 6.

Further, after determining the positional relationship between the control channel resources and the data channel resources of the target resource pool, the resource pool configuration information may further include that the control channel resources and the frequency domain resources of the data channel resources are adjacent or non-adjacent. And / or information that the control channel resource and the time domain resource of the data channel resource are adjacent or non-adjacent.

For example, when it is determined to adopt a frequency division multiplexing manner, the resource pool configuration information includes information that the control channel resource and the frequency domain resource of the data channel resource are adjacent or non-adjacent.

The number of OFDM symbols included in TTI can be an integer multiple of 14, for example. The number of TTI contained in a certain time unit can refer to the number of TTIs contained in a time length of 1ms or 10ms. Signal prefix The length is, for example, the time length of the cyclic prefix of the signal, or whether the cyclic prefix uses a conventional (Cyclic Prefix, CP) or an extended CP.
